close

close events are generated by several APIs:

HTML DOM

Sent to a target <dialog> to let it know that it has been closed.

IndexedDB API

Sent to the IDBDatabase object representing a database connection when the database is unexpectedly closed. This happens after all transactions have been aborted. You can use IDBDatabase.onclose to establish the event handler.

WebRTC API

Sent to an RTCDataChannel to let it know that a data connection has been terminated. You can use the RTCDataConnection.onclose property to establish an event handler for this, in addition to using addEventListener().

WebSocket API

Sent when a WebSocket connection closes. More information needed here.
